IMPROVEMENT IN BRAlD-GUIDES FOR SEWING-MACHINES.

Specification forming part of Letters Patent No. 156,l54, dated October20, 1874; application filed August 26, 1874.

To all whom it may concern:

Be it known that I, CHRISTOPHER GULL- MANN, of the city, county, andState of New York, have invented a certain new and useful Improvement inBraid-Guides for Sewing- Machines, of which the following is aspecification.

This invention consists in combining, with the throatplate of asewingmachine, two jaws, which turn on a common pivot, so that they canbe opened or closed to correspond to the width of the braid passingthrough betwt en them, the shanks of said jaws being provided withcam-slots and recesses to engage with a cam or button, by turning whichthe jaws can be readily opened or closed, and the guides can be adjustedfor braids of various widths, said button and cam slots being shaped ashereinafter described, so that the jaws are locked in any position inwhich they may be brought.

This invention is illustrated in the accompanying drawing, in whichFigure 1 represents aplan or top view. Fig. 2 is an inverted plan,partly in section, the line w 00, Fig. 4, indicating the plane ofsection. Fig. 3 is a similar view of the same, the line y y, Fig. 4,indicating the plane of section. Fig. 4 is a vertical section in theplane 2 2, Fig. 1. Figs. 5 and 6 are detached views of the two jaws,which constitute my braid-guide.

' Similar letters indicate corresponding parts.

In the drawing, the letter A designates the throat-plate of asewing-machine, which is provided with an aperture, to, for thefeed-dog, and with a throat, b, for the needle. With this throat-plateare combined two jaws, c d, which swing on a common pivot, e, and one ofwhich is provided with lips f, (see Fig. 5,) which extend over the otherjaw, so as to form a channel, through which the braid can be fed to andunder the needle of the sewing-machine. The jaw c, Fig. 5, consists oftwo arms, one of which is secured to the pivot 6 above the throat-plate,while the other arm, 0*, is fastened to said pivot beneath thethroat-plate, and at such a distance from the same that room is left forthe arm d Figs. 4 and 6, of the jaw 01. In the ends of the arms 0* and61* of the jaws c and d are formed eyes 9 h, Figs. 5 and 6, which areprovided with recesses ij, to engage with pins .k Z, which project fromthe head of a button,

in, on opposite sides of the center of said button, so that by turningsaid button the jaws 0 and d are opened or closed, and by the button thesaid jaws are locked in any position into which they may be brought. Thebutton m is provided with two heads, one above and the other below, sothat it can be turned from either end.

By turning the button at the jaws c d are opened or closed, and theguide is readily adjusted for braids of different widths, and I amenabled to sew a braid of any desired width to the under side of anyfabric as the same passes through the sewing-machine.

What I claim as new, and desire to secure by Letters Patent, is-

The jaw 0, having an arm, 0*, and a lip,f, and jaw d, having an arm, deach of said jaws provided with eyes 9 h and recesses '6 j, incombination with a button or cam, on, having pins k Z, and thethroat-plate of a sewing-machine, substantially as described.

In testimony that I claim the foregoing I have hereunto set my hand andseal this 19th day of August, 1874.

CHRISTOPHER GULLMANN. [L. 8.]
